[Asterisk-Users] GSM to g729 Conversion

[Michael Loftis]

app_voicemail uses ast_streamfile or related.  so no changes would be 
necessary.  if it finds a file already encoded in the correct type for the 
channel it's about to play on it'll prefer to use that file instead of 
attempting to transcode.  when transcoding i believe it will also prefer to 
transcode a .wav (which * writes as uncompressed g711 ulaw IIRC) to the 
needed codec rather than decompress and recompress say a GSM encoded file.
